possible head swap. new answers first tho
I havean 89 xj with the 4.0 and I want to kno if I can put the head and intake from a newer model xj on with out a lot of issuses. Somebody help please
Not without doing a lot of extra work. You're going from Renix to HO so the engine management is different. Ports are different too. Much easier to swap the motor entirely or swap a Renix head to your Renix block.
